Patented May 31, 1932 UNITED STATES JOHN HERBERT HANLON, OF LYNN, MASSACHUSETTS DETACHABLE LOADING MACHINE Application `1ed April 28,

This invention relates to improvements in loading machines of the endless bucket type and particularly to a machine which may be detachably secured to a conventional dump truck body, preferably to the tail gate thereof. Briefly the invention consists of a bracket adapted to be hooked over the tail gate of a truck and an endless bucket elevator adjustably carried by the bracket and driven by a small gas engine secured thereto.

A preferred embodiment of the invention is shown in the accompanying drawings, in which:

Fig. 1 isa side elevation of a machine constructed in accordance with my invention.

Fig. 2 is a rear elevation of the same.

Fig. 3 is a top plan view of the same with parts removed.

' Fig. 4 is a side elevation of the attaching bracket. J

In the drawings 1 indicates the body of a conventional dump truck which is provided with the usual tail gate 2. The attaching or supporting bracket of the loading machine is indicated in its entirety by the numeral 3 and consists of two side plates or members 4 which are connected by an integral memh ber 5 provided with a hook portion 6 whereby the bracket may be hooked over the tail gate 2. Set screws 7 threaded through hook portions 6 provide means for clamping the bracket to the tail gate. Two channel members or guides 8 are bolted to the outer end of each side plate for a purpose later to be l5 described. A

The endless bucket elevator is indicated as a whole by the numeral 9 land consists of two side frame or channel members 10 the upper and lower ends of which are connected by shafts 11 journalled therein. Mounted on these shafts are sprocket wheels 12 over which run endless chains 13 carrying digging and conveying buckets 14. The upper end'of the elevator carries an inclined chute 15 to re- 5 ceive material elevated bythe buckets and in normal operation the lower end of this chute overhangs the truck body 1 so as to discharge material thereinto.

The elevator 9 is secured to the bracket 3 through the medium of the guides 8 which the pile.

embrace the frame members 10 and secure them in slidable engagement with the side plates 4. Means is provided for adjusting the elevator vertically relative to the bracket as follows. J ournalled in the side plates 4 of the bracket is a shaft 16 keyed to which adjacent the outside of one of the side plates is a ratchet wheel 17. Mounted on the said side plate for engagement with the ratchet wheel is a pawl 18. One end of the shaft is provided with a crank 19. Secured at one end to the shaft andiwound thereon is a cable 2O the other end of which is fastened to a rod or member 21 which is connected to the frame members 10 intermediate their ends. By turning the crank the elevator may be raised or lowered relative to the bracket and held in suc-h adjusted position by the pawl and ratchet means.

The following means are provided for driving the bucket chains 13 mounted on the tops of the frame members 10 and secured thereto is a bracket 22. Carried by the bracket is a small gas engiiie 23 which is connected to drive the upper sprocket shaft 11 by means ofreduction gearing 24. By the use of the reduction gearing as shown an engine of liglt weight and low horsepower may be use In operation the bracket 3 is secured to the tail gate 2 and the elevator 9 is then adjusted to the desired relation with the ground by means of crank 1 9.A The engine 23 is then started and the buckets 14 are operated to elevate the material to be loaded and deposit it in the truck body. When loading a pile of material the elevator may operate while the truck is stationary, or the truck may be slowly backed so as to Work the elevator into When the truck is loaded, the loading machine may be removed by detaching the bracket 3, or it may be left in place while the material is transported. When the body is raised to dump the material the loading machine will swing free with the tail gate.

The advantage of this machine lies in its lightness and simplicity, and in the fact that it may be quickly and easily attached to any conventional dump truck.

I claim as my invention:

1. In a loading machine, an endless bucket elevator having side frame members, a supporting bracket therefor, said bracket being provided with guide members in which said side frame members are slidably received, and a hook portion on said bracket whereby it ma be detachably secured to a truck body.

2. n a loading machine, an endless bucket elevator having side frame members, a supporting bracket therefor, said bracket being provided with guide members in which said side frame members are slidably received, means carried by said bracket and connected to said elevator for vertically adjusting the elevator relative to the bracket, and a hook portion on said bracket whereby it may be detachably secured to a truck body.

3. In a loading machine, an endless bucket elevator, a supporting bracket for slidably receiving said elevator, means for vertically adjusting said elevator relative to said bracket, said bracket having a hook portion for detachable connection to a truck body.

' 4. In combination with a truck body having a tail ate, a bracket havin a hook portion Where y it maybe detacha ly connected to said tail gate, and an endless bucket elevator adjustably carried by said bracket.

5. In a loading machine and as a sub-combination thereof, a bracket having spaced side plates, guide means secured to said side plates, and a. member connecting said side plates and having a hook portion whereby the bracket may be detachably connected to al truck body.
